     <p>
-      SuperTux is a 2D game very similar to Super Mario with Tux Penguin as
-      protagonist, you must end each level by jumping and running to avoid
-      obstacles and enemies.
+      Run and jump through multiple worlds, fight off enemies by
+      jumping on them, bumping them from below or tossing objects at
+      them, grabbing power-ups and other stuff on the way.
+    </p>
+    <p>
+      In addition to the Story Mode, there is a large amount of
+      community contributed levels available as add-ons or in the
+      forums. Everyone can contribute such content by using the
+      integrated level editor.
